Specification of Letters Patent.

Patented Aug. 2, 1ero.

Application filed April 20, 1910. Serial No. 556,533.

To all whom it may concern:

, useful Improvements in Cornllusking Mas a `machine of this class which shall possess chines, of which the following is a specification.

This invention relates to corn husking' machines, and it has for its object to produce superior advantages in oint of simplicity, durability and general e ciency.

A further ob]- ect of the invention is to prov vide'simple and ecient means for cutting or chopping the stalks from the ears or from the ear Carrying portions and permitting the latter to drop to the husk stripping mechanism.

A further obj ect of the invention is to provide simple and efficient means for loosening` the husks upon the ears before engaged by the stripping rollers.

With these and other ends in view which will readily appear as the nature of t-he invention is better understood, the same consists in the improved constructionand novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

ln the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modications within the scope of the claims may be resorted to when desired.

In the drawings,-Figure l is a top plan view of a machine constructed in accordance with the invention. Fig. 2 is a longitudinal vertical sect-ional view of the same. Fig. 3 is a vertical transverse sectional view taken on the plane indica-ted by the line 3 3 in Fig. 2. Fig. 4 is a vertical transverse sectional view taken on the plane indicated by the line 4-4 in Fig. 2. Fig. 5 is a side elevation. Fig. 6 is a side elevation taken from the opposite side. Fig. 7 is a detail view in elevation on a larger scale of the cutting device carried by the shaft 29, the latter being shown in section.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame of the improved machine in- .cludes side members 1, 1 which are suitably connected and spaced apart b cross bars to which reference will hereinafter be made. The side members, while represented as be ing solid, may obviously consist of skeleton castings for the purpose Of securing the necessary strength without excessive weight.

A cross bar 2 which constitutes a part of i the main frame structure serves to support rearwardly extending frames A, each consisting of arms or side members 3, 3 connected at 'their rear ends by a cross piece 4 having a recess 5 provided with a beveled edge 6. The arms 3, 3 are also connected adjacent to the cross piece 4 by a yoke 7 which cooperates with the recessed cross piece to form a guide for the cut ends of the stalks that are being fed to the machine.

The side members of the main frame are provided with bearings for shafts 8, 9 which are disposed one above the other in rear of the cross pieces 4. Said shafts are provided with corrugatedfeed rollers 10, 11 arranged in rear of the feed frames, the rollers 10 of the upper shaft being equipped with circular cutting disks 12 engaging annular grooves 13 in the lower rollers 11. These feed rollers take hold of the butt ends of the stalks that are being fed over the feed frames and carry the stalks in a rearward direct-ion, serving at the same time to mash the stalks and to split or shred them longitudinally.

A shaft 14 supported transversely in the frame of the machine below the feed frames is equipped with saw toothed cutting disks 15, said disks lying beneath the frames A. A series of shafts 16 are arranged in an inclined plane below the frames A and the.

shaft 14, the uppermost shaft 16 being closely adjacent to the rear ends of the frames A, while the lowermost shaft 16 is disposed below the shaft 14. The several shafts 16 are equipped with saw toothed disks 17 which are rotated reversely to the disks l5 and coperate therewith to slit or loosen the husks of the ears of corn dropping therebetween.

Cross bars 18 and 19 forming part of the frame structure adjacent the front and rear ends, respectively, are provided with bearings for shafts 20, 20 carrying the stripping rollers 21, 21 which arepreferably covered with rubber, as'shown at 22. The cross bars 18 and 19 are so located that the roller carrying shafts will be disposed in a downwardlyl and rearwardly inclined plane. One shaft .20 of each pair or set of rollers is equipped with a bevel gear 23 meshing with a corresponding bevel gear 24 upon a transverse shaft 25 in front of the cross bar'18.

A cross bar 26 forming part of the frame structure below the shaft 9 supports an upright 27 having a slot 28 for the passage of the shafts 8 and 9, and said upright, together with the cross bar 2, serves to support a longitudinally disposed shaft 29 having an outwardly extending arm 30 at the outer end of which is supported a shaft 31 carrying a cat-ting disk 32 and a sprocket wheel 33, the latter being connected by a chain 34 with a sprocket wheel 35 upon the shaft 29 from which latter rotary motion will thus betransmitted to the shaft 31 carrying the cutting disk. The arm v30 :is of such length that the cutting disk 32, which is supported for-'orbital mov-ement, will pass adjacent -to the cross bars 4 and yokes 7 of the frames A, A alternately, as will be readily understood. It will likewise be understood that the stalks which are fed over the respective frames will be engaged by the rotary critter 32 as it descends at one side of the machine and as it ascends at the other side of the machine, the stalks engaged by the cutter in its ascending movement being supported by the yoke 7 so as to positively prevent displacement of the stalks by the cutter.

A main 1drivin-g shaft 3,6 isl supported for rotation .adjacent to one end of the frame, and moti/on is transmitted from said shaft by a chain 37 to the shaft 8 which latter is connected with the shaft 9,1 by intermeshing gears; 3:8. From the shaft 9 motion is transmitted by a chain 39 to the shaft 14 carrying the cutting disk 15. From the opposite end of the .shaft 8 motion is transmitted by a-n endless chain 40 to the cutter carrying shafts 16, to the shaft 25 and also to a shaft 41 which is supported foil rotation adjacent toy the end of the machine. Idlers 42 may be employed for'tightening the cha-in whereever it shall be deemed necessary order to insure efficiency of operation. The shaft 41 carries a disk 43 having several concentric Seri-es of beveled teeth 44, any one of which Series may be placed in engagement with a bevel pinion 45- upon the shaft 29 to which rotation may thus be imparted at various speeds. The disk 44, as well as the pinion 45, are movable upon their respective shafts where they may be held in adjusted position by set screws 46. The pinion may thius be placed in mesh with any one of a series of teeth 44 for the purpose of varying the speed. Motion is impartedV to the stripping rollers from the shaft 25 by the intermeshing; bevel gears 23, 24.

From the foregoing description taken in` connection with the drawings, the operation and advantages of this invention will be readily understood by those skilled in the art to= which it appertains.. Stalks fed' over i the feeder frames A with their butt ends to the rollers 10, 11 will be assisted by said rollers and carried therebetween, being crushed by the rollers and slit or shredded longitudinally by the cutters 12. The butt endsaresevered by the rotary cutter V32, and

' the ears will drop upon the inclined series of cutters 17 which Vcoperate with the cutters 15 to shred and to loosen the husk before the ears drop upon the strip-ping. rollers, which latter will seize ,hold of the hnsks. rThe husks are carried downward between the stripping rollers and the ears will slide downwardly along the latter, being 4eventually discharged yat the tail end of the machine.,

It is obvious that a suitable conveyer may be employed to :carry olf the. stalks `after .being crushed :and shredded, but such conve-yers are in coinlmon use, and itl hasnifiotni.;.i

been deemed? necessary to illustrate the same.

Having thus described the invention what is claimed as new, ist- 1. In a machine of the characterdescribed, stalk engaging crushing rollers, a pair of feeder frames disposed in advance of the same and havingv recessed vcross bars, one of said feeder frames being equipped with a stalk retaining yoke, a shaft supported Vfor rotation intermediate the feeder frames, an arm extending radially from the shaft and carrying a rotary cutting disk, and meansfor imparting rotary motion: to: said disk from the shaft when thelatter is rotated..
